In a recent video, Dave used what he referred to as the "mystery multimeter". It has the same blue coloured encasing as the Brymen 235 rebranded meter. As another user pointed out, there are many other features that Dave likes:

Yes, Dave has been working on this for a while. It's a 100% Dave designed meter rather than a co-branded meter like the Brymen. They have been sneaking their way into the videos over the last month or so, but this last video is definitely the most open appearance. He used a "super secret meter" at one point that had a 15V diode tester, so that's probably on the list of features.

Dave mentioned in the Batteroo live stream that he was waiting on a final prototype (probably the one shown in the video you are referring to since it should be here by now), and after testing it Dave is expecting to be ready for a public unveiling. (Sorry, I'm too lazy to find a time stamp for any of this)

In the latest mailbag Dave also gave a hint as to the microcontroller it will be powered by (STM32...) Not far away now! I've been holding off getting the Bryman meter in waiting for this much anticipated Dave DMM...

It is?

I thought so. This is one of those things where I've picked up bits of information here and there but can't really remember where any of it came from, so I guess I should be careful what I say. I do believe he has been much more involved in the design of this one at the very least.

Yes, 15V diode test.Not entirely true that it's 100% designed by me. I set the specs, and a multimeter company is doing the actual design. But I am getting nitty gritty on the circuit level though.There is only so much I can do, and many compromises have had to be made, and I've had to let a few things slide that I would have fixed myself if it was me doing the design. But it's hard to go back and forth on tiny changes like that, you can't micro-manage a design team you have no direct contact with.I'd love to actually blog the process but I can't.

Supposed final prototype is on a truck somewhere.I have 4-5 other prototypes that look identical, just some minor tweaks on the new one.

In addition to what I said above, yes this is designed from scratch exclusively for me. It's not based on any previous design.One thing they wanted in the contract though, is they liked the compact 4xAA battery housing I specified and they came up with, so they wanted permission to re-use this on other (non-competing) products of theirs. So you might see the case used in other products.

Intertek Group plc is a multinational inspection, product testing and certification company headquartered in London, United Kingdom.

Intertek can trace its origins from a marine surveying business formed by Caleb Brett in the 1890s, a testing laboratory formed by Milton Hersey in Montreal in 1888 and a lamp testing centre established by Thomas Edison in 1896.

I see from the PCB print that it has 2 fuse holders. Does that mean abandoning the single fuse mosfet solution you spoke of in #931 was one of the compromises? Or does this sample predate the concepts discussed in that video?

Pre-production working sample shown in the last mailbag has two current inputs, therefore two fuses presumably. 10A and 500mA? (input jack has 400mA screen printed on it).
